Benefits of technology

"The invention introduces a new approach to proofing that reduces errors and saves time in high-volume printing. It uses a system that automatically enforces certification standards and prevents costly and time-consuming errors. The system detects and identifies features of the proofing process that affect quality, and can prevent misuse of the system by educating operators and documenting the certification standards. It also allows for simultaneous detection of multiple types of certification information and efficient tracking of recalls and bad stock. The method includes receiving a printable sheet, automatically detecting features of consumable components of the proofing process, evaluating the results of detection, and printing print data on the sheet in response to a positive result. The invention also provides a way to generate a certification notice on the printable sheet."

Problems solved by technology

It is believed based on analysis of field service reports that a large part of the most troublesome proofing errors are caused by human errors and / or possibly well-intentioned tampering.
Indeed, even the most scrupulous operators are not perfect, and may occasionally select inappropriate substrates or put them in upside-down, for example.
And inexperienced or distracted operators may also make more serious errors, such as soiling proofers and proofs by reinserting used substrates that cannot absorb the excess ink deposited on them.

Embodiment Construction

[0056]Referring to FIG. 1, a certified proofing system 10 according to the invention includes a physical certification sensing system 12 and a proofing subsystem 14 that are used to create proofs of print jobs to be printed on a reference printer or “press”36. The proofing system is preferably implemented at least in part as a physical proofing plant that can take the form of an enclosed standalone machine built on a frame that supports circuitry and mechanical elements. The physical proofing plant also preferably has a computer interface enabling it to be connected to one or more remote computers.

[0057]The proofing subsystem 14 includes a proof certification engine 26, a proofing engine 28, an image processing engine 30, proof certification standard storage 32, and print data storage 34. Although the physical certification sensing system and the proofing subsystem are preferably implemented within the physical proofing plant, some or all of the functionality of these elements may b...

Abstract

A certified proofing method is disclosed that includes receiving a printable sheet and automatically detecting at least one feature of at least one component of a proofing process bearing on its quality. The method also includes automatically evaluating at least one result of the step of detecting, printing print data on the printable sheet, and generating a certification notice for the printable sheet in response to a positive electromagnetic result signal from the step of evaluating.

Description

FIELD OF THE INVENTION[0001]This application relates generally to proof printers, such as inkjet proofers.BACKGROUND OF THE INVENTION[0002]Proofing is a crucial step in high-volume printing operations. This is because high volume printing presses are typically expensive to set up and run, and they generally cannot be stopped before hundreds or even thousands of pages have been consumed. And if an error is not detected until after a whole run is complete, millions of pages can be wasted. Printing professionals therefore commonly use dedicated ink-jet proof printers to create so-called “contract proofs,” which they present to their customers for approval before beginning high-volume printing runs.[0003]Given the potential costs at stake, it is of the utmost importance to ensure that these contract proofs match the final output. To this end, the print data are color corrected so that the inks used on the proof printer can accurately match the colors in the final output. The data may al...
